Agreed. Note though that the Ubuntu live installer has a "Try" mode that gives you a nearly normal desktop experience without installing, and is an effective test environment to discover what will work and what won't. Wifi, graphics and suspend are worth trying out this way.
One thing I didn't have major issues with was my Nvidia graphics card, which was a surprise.
- wake from suspend - laptop power consumption - poor wayland support - sudden desktop restarts - hidpi, external monitors, virtualization
Nvidia's proprietary crap has always worked badly, the re-implement everything and put all their development effort into NIH syndrome instead of playing along with the already existing open source stack.
Now I'm a desktop user, so the first two don't really impact me, and the rest has been working fine for the ~2 years I've been in Wayland+Arch+Gnome across 3 different NVIDIA GPUs. Not sure why virtualization is there, but it also seems to work, although via WSL2 is slightly buggy, but I blame that on Microsoft rather than Linux/NVIDIA.
As to sudden restarts, this has never happened to me.
